http://devilmaycry.org/threads/official-incoming-dmc-art-book-reveals-vergil-is-neros-father.15205/page-2#post-459325 OK, this is grade A material, which does support any theory, but still makes Nero related to Vergil more directly. Since I can't read Japanese, sadly, I had to trust an online forum, but multiple posts indicate that the phrase is there. DMC is lousy with actual DATES, and here I'm bringing out the next thingy - it couldn't have been several months between TAS and 4, because Lady is incredibly different in 4 (yes, Doylian would just reason that the only point of reference then was DMC 3 Lady, but Watsonian won't accept such an excuse). Dante is what, 18, 19 in DMC 3? And he looks rather older in 4 than in 1, not by months, really (also, I've never seen stubble on a Japanese character who was younger than 30 at least), but by years, he's 35, maybe. It makes it plausible for Nero to have been conceived and born before DMC 3, and that fits very well with his 17-18 age, if we assume Dante is indeed in mid-thirties during DMC 4. Hell, Nero isn't necessarily Vergil's direct child, he may be a clone (surprisingly realistic one, actually, because you get babies from cloning, not grown-ass humans) but he still is Vergil's heir as far as series are concerned.
